• Phosphonium-based aminophosphines as bifunctional ligands for sequential catalysis of one-pot hydroformylation–acetalization of olefins

  involved bifunctional moieties of the phosphine fragment and Lewis acidic phosphonium were linked together by stable chemical bonds and bridged by one N-atom. The molecular structure of the L2-ligated Rh-complex (Rh-L2) indicated that such bifunctionalities were well retained without incompatibility problems. Investigations on co-catalysis over L1–L3 showed that L3 exhibited the best sequential catalysis

  制备并充分表征了一系列基于离子phospho的氨基膦L1 - L3，其中每个膦片段的双功能部分和路易斯酸性phospho通过稳定的化学键连接在一起，并通过一个N原子桥接。与L 2连接的Rh-络合物（Rh-L 2）的分子结构表明，这样的双官能团被很好地保留而没有不相容性问题。在L1 - L3上进行共催化的研究表明，L3在加氢甲酰化和乙缩醛化方面均表现出最佳的顺序催化。L3中的膦片段与Rh配合物一起负责加氢甲酰化反应，而as则充当路易斯酸催化剂，负责乙缩醛化反应。该L3 -Rh（ACAC）（CO）2系统也显示出良好的通用大范围在不同的醇的烯烃的加氢甲酰化，缩醛化。

  A solid catalyst for olefin polymerization and a process for producing an olefin polymer are provided. The polymer has a small content of a component which is dissolved out into a low temperature organic solvent, such as a low-molecular weight component and an amorphous component. The solid catalyst is obtained by bringing a solid catalyst component for olefin polymerization containing a titanium atom, a magnesium atom, a halogen atom, and an aliphatic carboxylate; an organoaluminum compound; and a compound represented by formula (I) into contact with each other: wherein R 1 is a hydrocarbyl group having 1 to 10 carbon atoms, R 2 is a hydrogen atom, a halogen atom or a hydrocarbyl group having 1 to 16 carbon atoms, and the R 1 the R 2 groups are independently the same or different, and the respective R 1 groups and R 2 groups may be joined with each other to form a ring.

  Hydroformylation of terminal alkenes in alcohol solvents leads to the selective formation of the corresponding acetals. The Xantphos ligand gave the best results as well as acetal selectivities higher than 99% and linear/branched ratios of up to 52 were obtained. The scope of the reaction was studied. Acetals were found to be unreactive under hydroaminomethylation conditions.
